Part 00311 Ball Cage is a precision-molded component designed for SprayTech EP2300 series sprayers. The ball cage houses and guides the ball in the priming or pressure relief system, ensuring proper seating and unseating during operation. Replacing a worn, cracked, or deformed ball cage restores consistent priming and prevents pressure fluctuations.

The 00311 Ball Cage is an engineered component that houses the check ball within the fluid section of SprayTech EP2300 series sprayers. It provides a guided path for the ball to seat and unseat during the priming and pressure relief cycles, ensuring one-way flow and maintaining system pressure.
Over time, chemical exposure, wear, or impact can cause the cage to crack, warp, or develop rough surfaces that impede ball movement. A damaged ball cage can lead to slow priming, pressure loss, or complete failure to build pressure. Replacing it with this OEM-specification component restores proper fluid control.
| Ball guidance | Keeps the check ball aligned with the seat for proper sealing |
|---|---|
| Flow control | Allows fluid to pass in one direction while preventing backflow |
| Retention | Holds the ball in place within the fluid section |
| Pressure maintenance | Supports consistent system pressure during operation |
| Cracks or breaks | Visible damage to cage structure |
|---|---|
| Worn internal surface | Smooth or grooved interior that no longer guides the ball properly |
| Ball sticking | Ball fails to move freely within the cage |
| Priming failure | Sprayer won't prime or loses prime during use |
This ball cage is designed for the following SprayTech models. Always verify your equipment's parts diagram to ensure correct fit.

When servicing the ball cage, these associated components are often inspected or replaced at the same time.
If the ball is pitted, worn, or out of round, replace it simultaneously.
A worn seat prevents proper sealing even with a new cage and ball.
Replace if distorted or weakened to ensure secure ball retention.
